The short answer
A claim is what you file with a payer when you're in-network (or courtesy-billing out of network); the payer pays you. A superbill is a detailed receipt you hand a cash-pay client; the client files it with their own insurer for out-of-network reimbursement, and any money goes to them. A cash-pay client needs a superbill only if their plan has out-of-network benefits — typically a PPO. Clients on HMOs, EPOs, and most Medicaid plans usually have nothing to submit it to.
"Do you take insurance?" has more than two answers, and the middle one — "no, but I can give you a superbill" — is where most of the confusion lives. Here is how the two documents differ, and a short intake script for figuring out which one each client actually needs.
| Claim | Superbill | |
|---|---|---|
| Who files it | You (or your biller/EHR) | The client |
| Who gets paid | You, per your contract | The client, if the plan reimburses |
| When it applies | In-network, or OON courtesy billing | Cash-pay client with OON benefits |
| Your obligation | Contractual rules, timely filing | Accurate document; the rest is the client's |
The deeper pipeline behind claims — clearinghouses, ERAs, denial codes — is its own topic, covered in insurance billing, explained. This article is about the fork in the road: which document does this client need from you?
"What kind of plan do you have — a PPO, an HMO, or something else?" That single question sorts most clients:
Encourage the client to confirm with the number on their card: "Do I have out-of-network benefits for outpatient mental health, what is my out-of-network deductible, and what percentage do you reimburse after I meet it?" Three questions, five minutes, and they know what a superbill is worth to them before the first invoice.
Insurers reject superbills for missing fields far more often than for substantive reasons. A usable superbill needs:
The field-by-field breakdown, with a worked example, is in the superbill template guide. Or generate one directly — the free tool below produces a complete superbill you can download and hand to a client.
Fill in the provider, client, and session fields and it assembles a submission-ready superbill. Free, runs entirely in your browser — nothing is uploaded.
Open the full tool in its own tab.
The kindest thing you can do for a superbill client is deflate the fantasy early. Say some version of: "I'll give you a monthly superbill. Whether your plan reimburses — and how much — depends on your out-of-network benefits and deductible, and I can't promise an amount. Most plans that do reimburse pay a percentage of what they consider a reasonable rate, which may be less than my fee." A diagnosis code is also required on the superbill, which means a diagnosis enters their insurance record — some cash-pay clients choose privacy over reimbursement once they know that, and it is their call to make.
One more obligation runs the other way: cash-pay and uninsured clients are generally entitled to a Good Faith Estimate of expected charges under the No Surprises Act. That is separate from the superbill and has its own rules — see the Good Faith Estimate guide.
Courtesy billing — you file the out-of-network claim on the client's behalf — is the third option. It saves the client the paperwork and gives you visibility into what the plan actually does, at the cost of your admin time, and some plans still send the check to the client. It is a service decision, not an obligation. Many practices land on a simple policy: superbills for everyone who wants one, courtesy billing for nobody or for a small number of clients where it clearly matters.
In Practice Harbor, superbills are assembled from the sessions you already documented — codes, diagnosis, and payments included — and shared to the client portal in a click.
A claim is filed by the provider with a payer, and the payer pays the provider under a contract. A superbill is a detailed receipt the provider gives to a self-paying client; the client submits it to their own insurance for out-of-network reimbursement, and any reimbursement goes to the client. The provider’s only obligation on a superbill is that it be accurate and complete — the filing, follow-up, and outcome belong to the client.
No. A superbill is only useful to clients whose plans include out-of-network benefits — most commonly PPO plans. HMO and EPO plans generally do not reimburse out-of-network outpatient therapy, and Medicaid plans generally offer no superbill reimbursement path. Ask each client what plan type they have at intake, and suggest they call their insurer to confirm out-of-network mental health benefits before counting on reimbursement.
Provider name, credentials, NPI, tax ID, and practice address; client name and date of birth; the date, CPT code, place-of-service code, and fee for each session; the amount paid; and an ICD-10 diagnosis code. Missing NPI, diagnosis, or place-of-service fields are common reasons insurers return superbills unprocessed.
No, and it is important to say so plainly. Reimbursement depends on whether the plan has out-of-network benefits, whether the out-of-network deductible has been met, and the plan’s allowed amount for the service — which may be below the therapist’s fee. A superbill makes reimbursement possible where benefits exist; it never guarantees it.
